A valve having a function of entrance selection is provided to selectively use purified or unpurified water without an additional faucet or a change of the faucet. A valve having a function of entrance selection includes a raw water inlet(10), a raw water outlet(20), a raw purified water inlet(30), a raw water passing unit(40), a raw water and purified water outlet(50), and an opening and closing device(60). The direction of water is changed by turning or pushing the opening and closing device. The opening and closing device is installed between the raw water outlet and the purified water inlet or at the raw water outlet. The raw water passes through the raw water outlet, a water-purifying device(70), and the purified water inlet sequentially in case of closing of the opening and closing device. The raw water passes through the raw water passing unit in case of opening of the opening and closing device.
